Abstract: In a method of generating a virtual 3D model of a dental site, scan data comprising a plurality of images of a dental site is received during an intraoral scan. An analysis of an image is performed. A representation of a reference object with known properties is identified in the image based on the analysis. A virtual 3D model of the dental site is generated based on the plurality of images. The image and/or the virtual 3D model of the dental site is modified by adding additional data about the reference object to the intraoral image and/or the virtual 3D model based on the one or more known properties of the reference object. If the image is modified, it may be modified prior to generation of the virtual 3D model, and the virtual 3D model may be generated using the modified image.

Abstract: Aligners and associated systems are provided. In some embodiments, an aligner includes a three-dimensionally (3D) printed shell. The 3D printed shell can include an interior surface having a plurality of tooth-receiving cavities shaped to reposition a patient's dentition from a first arrangement toward a second arrangement, and an exterior surface disposed opposite the interior surface. The aligner can also include one or more elastic regions directly fabricated on the 3D printed shell. When the aligner is worn on the patient's dentition, the aligner can apply one or more forces onto the patient's dentition via the one or more elastic regions to affect repositioning of the patient's dentition from the first arrangement toward the second arrangement.

Abstract: A system comprises an image capture device, an augmented reality (AR) display to display, and a processing device. The processing deice receives image data of a dental arch from the image capture device and processes the image data using a plurality of detection rules, where each detection rule detects one or more dental conditions. The processing device determines a dental condition for the dental arch based on the processing, determines a position of an area of interest on the dental arch, wherein the area of interest is associated with the dental condition, generates a visual overlay comprising an indication of the dental condition at the position of the area of interest, and outputs the visual overlay to the AR display, wherein the visual overlay is superimposed over a view of the dental arch on the AR display at the position of the area of interest.
